wpf engineering value formatting

[eugenem]

In Measurement Studio WF there is engineering formatter:

NationalInstruments.UI.FormatString fs = new NationalInstruments.UI.FormatString(NationalInstruments.UI.FormatStringMode.Engineering, "S2");

Is there similar formatter in WPF? I've found only standard formatters like 

var fs = new GeneralValueFormatter("0.###");

Hi Eugenem

The closest thing I can find is the EngineeringFormatInfo class, although it's not a WPF element.

I don't believe there is currently a WPF string formatting class or namespace which is part of the Measurement Studio package.

Kind Regards

thanks! 

this one is good for manual formatting

how do I apply it to graph axis?

now I use 

ax.MajorDivisions.LabelPresenter = new GeneralValueFormatter( config.format );

Hi Again

I've taken another look and in WPF the graph formatting is done using XAML, unfortunately the only formatting options for the axis numeric that I can see are DateTime, Double, Int32 or PrecisionDateTime. i.e. the attached picture.

I think the answer to your original question is no for the moment.

Kind Regards

As Chris mentioned, the WPF controls do not currently support engineering format values. However, implementing a custom formatter using the EngineeringFormatInfo class is fairly trivial, and does not involve creating a new axis type.

See the attached file for an example implementation. You can use it in your code like so:

    ax.MajorDivisions.LabelPresenter = new EngineeringValueFormatter( "S2" );

Thanks, did it this way.
